My invention is a temporary broken spring support for motor vehicles,particularly adapted to support the springs in which a driving force istransmitted from an axle to the frame of the car through the springs instead of through radius rods or the like.

An object of my invention is to clamp the 7 spring structure adjacent anaxle and a part of the vehicle frame to which the free end of the springis connected by a flexible connecting device, so that broken springswill be sufficiently securedbetween the axle and the vehicle to permitcontinued travel.

In utilizingmy invention I use a' clamp which secures the broken leavesof a multiple spring together and has a flexible, cable with means tovattach same to the spring clamp or the like adjacent the spring axleand having means to secure the other end of the cable to the springbracket or the like attached to the frame of a vehicle. 7 7 My inventionis illustrated in the following drawings, in which: V

Fig. 2 is a perspective view of the temporary support detached from thevehicle,

Fig. 3 is a side elevation of a part of a vehicle showing another formof my attachment for a broken spring.

Fig.4-is a partial front elevation taken in the direction of the arrow 4of Fig. 3, and

Fig. 5 is a View of a flexible loop to be attached to the spring bracketon the frame.

In the drawings the frame of the vehicle is designated by the numeral 1,this being usually a channel having a bracket 2 attached thereto. Thevehicle axle is designated by the numeral 3 and has a spring 4 clampedthereto by U-shaped bolts 5 and clamping plates 6.. In this constructionof spring the main leaf 7 is attached to a pin 8 or the like whichpasses through the bracket 2. In the drawings the leaves of the springare indicated as being broken at the places 9 and 10 In order to make atemporary repair a clamp designated generally by the numeral 11 andcomprising lower and u per plates 12 and 13 secured by bolts B is p acedover the a; leaves of the spring, preferably as close to the breakaspossible. My'fiexible support desig natedby the numeral 14 isconnected-between the1U%boltsj5 and the bracket 2. :This sup-' portingdevice comprises aplate'15 having.

aperturesitherethrough tozbecsecurejd to the bolts-Bland. having: acable '16 with an; eye 17 attaching;sameztothe' plate. An eye 18 isforinedrat'. the other end of the cable and this engages: inithe eye;of" the tightening bolt 19,

this bolt ihavinga plate ZO, .which' plate fits. in front ofthe bracket2, and by :ineans-of-this nut: on Ft-he 5 bolt, it vis :tighten-ed untilthere" is .sufficient tension. on the. cable to .hold the brokenand-abutting ends of. the: leaves of the spring in firm relation one to.the. other and to clamp the spring sufficiently. tightly .so

that the vehicle may be used untilpermanent repairsz'canbe made.

. B'Ihe: construction shown in 3, 4L and 5 is usedawhere' the brackets 2are of such small sizeithatthe'bolt19'cannotibe placed through V same"between the iframeland: the pin 8. In a this iarrangement the flexible3100p 21 isffittedioven the front22rof thebracket 2 and is 1 hookedoveri-the pin 8, the @freeend of the loop: 23-ibeingi. suspended belowthe bracket.

LItiwill be noted" that in this surface of the spring, asindicated by the numeralQLfiand ZfOllOWS the contour of the springiWhile-Ihave illustrated my temporary supportfor broken springs asbeingconnected between the clamp which secures the spring to j the-axle-and abracket'on thevehicle frame,- it-is nevertheless obvious that 'thedevice could besconnectedto a swinging shackle'or thelike, and, ifdesired, couldbe connected construction the cable bears against thelower from'one endjof the spring toythe other. 112

is also manifest that; the supportingfdevice 'may bee-connected tocheep-rings in difierent v exert a compressive stress on the leaves ofthe spring.

It will be manifest therefore that my invention may be considerablychanged in general constructionand in specific detailsto adapt same todifferent circumstances and uses, such changes being 'Within the spiritof my invention as set forth in the description, drawing and claims.

I claim:

1. A spring support comprising, in combination, a vehicleframe having abracket, an v axle, a spring, bolts'securing the same to the axle, meanssecuring another part of the;

spring to the bracket, a flexible loop secured to the bracket, a cablehaving a plate securedi to the bolts, a tightening bolt on'ithe otherend of thecable, and means engaging said.

' bolt and the flexible loop.

nation avehicle frame having a bracket, an

2. A spring support comprising'in combiaxle, a'spring securing devicefor attaching thespring-tothe axle and to the'brackeha.

flexible cableihaving one end attached to a plate, the other end. of thecable having a directly connected threaded bolt, means to rigidly engagethe plate and the bolt to the devices securing the spring to the axleand to the bracket, respectively, the said lcable being adapted toextend along the side of the spring orto extend along the lowersurfaceof the spring.

3. A spring support comprising in 'co1n-' bination a vehicle 'frame"having a bracket,

an axle, spring bolts securing the spring-to the axle, meanssecuringanother' part of the spring'to the bracket, a'flexible cablehaving a plate at one end, the said plate being :rig-

idlysecured to one of the bolts attaching the i spring to the axle, athreaded" bolt directly 1- connected to the other end of the cable, and

means toy connect the threaded boltito the bracket, thesaid cable beingadapted-topass alongjthe sidefof the spring ortofollow :the'lowersurface ofthe spring. 4. A spri-ng support comprising incombinationa; vehicle frame having a bracket, an

, the spring and the axle, a threaded bolt directly attached to theother end of the cable, a

plate threaded on said bolt and means to connect the plate to thebracket and exert a ten sion 'onithe' bolt and on the cable, the said 7cable being adapted topass along one side of,

thespring or to follow the contour of the lower surface of the spring,
